Abstract
The utility model discloses a simple structure, effectually prevent because of the swelling capacity differently, bifurcated pipe return bend department is by the access door seal structure of drawing breakage, including the water -cooling wall, the water -cooling wall comprises one row of water cold wall pipe who is parallel to each other and the band steel of connecting the cold wall pipe that borders on the river mutually, and the band steel is arranged in the plane at water cold wall pipe central line place, and the rectangular hole has been offered to the centre of water -cooling wall, is provided with the bifurcated pipe that docks with water cold wall pipe respectively at corresponding both ends in the rectangular hole, link to each other through the connecting plate between the both ends center of adjacent bifurcated pipe, the connecting plate is provided with the dilatation joint respectively towards that end at water -cooling wall center, is provided with the sketch plate on the looks tangent plane between the tip of adjacent bifurcated pipe respectively. The utility model has the advantages that: connecting plate and sketch plate combine the back, both guaranteed sealed, again not can because of the different return bends of swelling capacity by the drawing breakage.
Description
Technical field
The utility model relates to the access door hermetically-sealed construction on a kind of waste heat boiler.
Background technology
Nonferrous smelting waste heat boiler has the characteristic of expanded by heating. Boiler becomes hot later from cold conditions heat absorption, produce a certain amount of expansion. Existing access door hermetically-sealed construction, comprise water-cooling wall, the water screen tube that water-cooling wall is parallel to each other by a row and the band steel that connects adjacent water screen tube form, band steel is arranged in the plane at water screen tube center line place, the centre of water-cooling wall offers rectangular opening, is provided with the bifurcated pipe that opposite ends is docked with water screen tube respectively in rectangular opening. Because the water screen tube in flue is always by the steam water interface water-cooled in pipe, thereby the wall temperature of the water screen tube of co-located and sealing plate is different, and thermal expansion amount is also just different, produces the larger bifurcated pipe bend pipe of sealing plate drawing crack attenuate amount.
For ensureing the normal operation of boiler, effectively prevent that sealing plate drawing crack bifurcated pipe bend pipe from being vital. In general design, the sealing plate between access door bifurcated pipe all seals bifurcated pipe pipe bent position, but in boiler actual motion, the phenomenon of the sealed plate drawing crack of access door bifurcated pipe pipe bent position often occurs, therefore this structure can not ensure the security of boiler.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of simple in structure, effectively prevent because of swell increment difference, bifurcated pipe pipe bent position is by the access door hermetically-sealed construction of drawing crack.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of access door hermetically-sealed construction, comprise water-cooling wall, the water screen tube that water-cooling wall is parallel to each other by a row and the band steel that connects adjacent water screen tube form, band steel is arranged in the plane at water screen tube center line place, the centre of water-cooling wall offers rectangular opening, in rectangular opening, be provided with the bifurcated pipe that opposite ends is docked with water screen tube respectively, between the center, two ends of described adjacent bifurcated pipe, be connected by connecting plate, connecting plate is respectively arranged with dilatation joint towards that end at water-cooling wall center, on phase tangent plane between the end of adjacent bifurcated pipe, be respectively arranged with sketch plate, sketch plate connects the end of adjacent bifurcated pipe, sketch plate is by dull and stereotyped and be arranged on dull and stereotyped one end and form to the arc of bifurcated pipe end center line bending.
Described dilatation joint is made up of with the circular seams being connected with rectangular slits end rectangular slits.
Described arc is all positioned at dull and stereotyped homonymy.
Described rectangular opening both sides and and between the adjacent water screen tube that is connected of bifurcated pipe be not also connected with baffle plate, baffle plate is arranged in the phase tangent plane of adjacent water screen tube.
The beneficial effects of the utility model are: connecting plate is positioned at bifurcated pipe two ends, not with the pipe bent position welding of bifurcated pipe attenuate amount maximum, and each piece connecting plate all has dilatation joint, after connecting plate is combined with sketch plate, both ensured sealing, again can be because the different bend pipes of swell increment be by drawing crack.

Detailed description of the invention
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4 and Fig. 5, access door hermetically-sealed construction described in the utility model, comprise water-cooling wall, the water screen tube 1 that water-cooling wall is parallel to each other by a row and the band steel 2 that connects adjacent water screen tube 1 form, band steel 2 is arranged in the plane at water screen tube 1 center line place, the centre of water-cooling wall offers rectangular opening 3, in rectangular opening 3, be provided with the bifurcated pipe 4 that opposite ends is docked with water screen tube 1 respectively, between the center, two ends of described adjacent bifurcated pipe 4, be connected by connecting plate 5, connecting plate 5 is respectively arranged with dilatation joint towards that end at water-cooling wall center, on phase tangent plane between the end of adjacent bifurcated pipe 4, be respectively arranged with sketch plate, sketch plate connects the end of adjacent bifurcated pipe 4, sketch plate is by dull and stereotyped 6 and be arranged on dull and stereotyped 6 one end and form to the arc 7 of bifurcated pipe 4 end center line bendings. dull and stereotyped 6 on the phase tangent plane between the end of adjacent bifurcated pipe 4.
Described dilatation joint is made up of with the circular seams 9 being connected with rectangular slits 8 ends rectangular slits 8. Can well cushion the impact of expanding and bringing.
Described arc 7 is all positioned at dull and stereotyped 6 homonymies.
Described rectangular opening 3 both sides and and between the adjacent water screen tube 1 that is connected of bifurcated pipe 4 be not also connected with baffle plate 10, baffle plate 10 is arranged in the phase tangent plane of adjacent water screen tube 1.
The utility model has the advantages that: connecting plate is positioned at bifurcated pipe two ends, not with the pipe bent position welding of bifurcated pipe attenuate amount maximum, and each piece connecting plate all has dilatation joint, after connecting plate is combined with sketch plate, both ensured sealing, again can be because the different bend pipes of swell increment be by drawing crack.
